Application led july 31,

The main object of this invention is to provide a boring brace having means thereon for illuminating the area in front of the drill or boring tool. l

Another object is to provide a boring brace having means thereon for villuminating the area around the tip of the drill or boring tool, which illuminating means may be selectively used, accordingly. as the time is l0 night or day, or under similar conditions.

AStill another object is to provide a rim tool for aiixing or removing automobile tires in the darkness. l

The above and other objects will become 15 apparent in the description below., in which characters of reference refer to like-named parts in the drawing.

l Referring briefly to the drawing, Figure 1 is a longitudinal sectional elevational 20 view thru` the boring brace, showing the .construction thereof in its entirety.

Figure 2 is Van external .top plan View of Figure 1.

Figure 3 is a wiring diagram of the il- 25 luminating means used with thev boring.

' brace.

Referring in detail to the drawing, the numeral indicates a hollow cylinder which forms the upper part of the brace and a chamber 11 contained in the cylinder is adapted to serve'as'storage room for a pair of dry cells 12 and 13 which are placed with their opposing poles end to end, as illustrated in Figure 1.f These dry cells 12and 13 are retained in place in the cylinder 10 by a coil spring 14 which urges said dry cellsl downwardly so that the pole of the lower dry cell lies in contact with a terminal stud 15 which is located at the bottom manently mounted on a collar 16 in which one end 17 of a tubular crank 18 is secured. The crank isU-shaped in outline and is ,l hollowthruout its length, and at the ositionconnecting the arms 19 and 19a o the crank and indicated by the numeral 20, a handle sleeve 21 isv rotatably mounted. Extending downwardly frorn lthe arm 19l of the crank, a head member 22 is secured to the end of the crank and extendsdownwardly parallel to the cylinder 10 and coaxial therewith and has a tapering square socket 23 therein'in which the end of a bit is secured by tightening down the thumb screw 55 24 which threadably engages the head 22.

of thehamber 11. This cylinder is perl 1925. Serial N0. 47,244.

Intermediate the length of the arm 19a andV extending angularly downward therefrom, a terminal member 25'is secured in said armj and connected to this terminal 25, is one end ot' a current carrying wire 26 which is i-n- 60 sulated from the crank 18 and passes thru portions and 19.01? the crank and has its opposite end connected to the terminal stud 15 which isalso insulated from'the crank 18 by a ange 27 The projecting portion 65 of this `terminal element isi contained within a spherical housing 28f--which is rigidly mounted and integral with a semicircular saddle 29` and has threads thereon at an opening above the spherical portion 70 which are engaged by a threaded ring 30 which serves to retain the glass lens ,31 in place. Beneath this glass lens within the housing 28, a reflector hood 32 is secured, and

in this reflector hood, afilament lamp 33 is 75 threadably mounted, the threaded shell socket 34 of the filament lamp being adapted to'th'read into an opening in the reilector hood and also serve as a terminal.

Slidably mounted Von the cylinder 10 is a 80 carriage 35 which is provided with downwardly extending.' pins to which one of the ends of a' resilient metallic finger 36 is secured. This metallic finger extends upwardly towardthe upper open end of the cylinder 10 and is bent' at its upperend so it may be readily urged into contact with the surface of a dished element. 37 on which thespiral spring 14 is mounted. This dished element is mounted on a cap 38 which 90, threadably engages the upper open end of the cylinder 10 and closes the latter and has rotatably mounted thereon a stud 39 on which a breast'support 40 is fixed.

This boring brace is provided with means which are adapted to illuminate the field around the -tip of the boring bit when the latter is being used in darkness. The housing 28 being mounted angularly, which angle extends toward the axis of the head 22 at 100 a position beneath the same, causes the bulb 33 when energized to illuminate the field around the lower end of the bit. When the circuit is open, the carriage 35 is in a position so that the resilient finger 36 does not Y 105 contact with the dished element 37. In order to close the circuit, this carriage 35 is urged toward the upper end-of the cylinder 10 until the resilient finger contacts with the edge of the lished element 37. i By aecompushing 11.0'

,terminals of the filament lamp this movement, the circuit is closed thruoutv the entire tool and courses in this manner. The current flows from the series arranged dry cells 13 and 12 thru the terminal stud 15 and thence thru the Wire 26 into one of the 33. The current then flows' thru the filament lamp, thru the socket 34, and thence is grounded thru the reflector hood, the housing 28, the entire crank member 18, and thence thru they cylinder 10 to the resilient finger 36, and

`into dry cell 13 thru the dished element 37 v marily desired to receive' a rim ,tool in said head which is used to remove. or mounttires .in platre onl the wheels ofv automobiles'or the like.l

I claim l l. Aj' device of the vclass-described comprising afcrank, a bit head at one end of said crank, a cylinder mounted at thel oppositerv end of said crank, said crank having a pair of ofi-set varms connected by an intermediate member, a housingon the lower arm, a

` saddle integral with said housing partly encircling said arm, said housing being mounted angularly on one of said arms, said angle extending toward, the axis ofthe bit head,

..a` llens `covering said housing a reflector hoodin said housing, a filament lamp mounted in .saidrelector hood, and means mounted in s'aidcylinder for illuminatingthe lamentlamp.

2. A device of the class described comprising a' crank, a bit head at .one end of said v crank, a cylinder mounted at the opposite end of said crank, said crank having a pair of off-set arms connected by an intermediate member, a. housing onthe lower arm, said housing being mounted angularly on one of said arms, said angle extending toward the axis of the bit head, a lens covering said housing, a reflector hood in said housing, a filament lamp' mounted in said. reflector hood, dry cells arranged in series'in said cylinder, a terminal mounted on one end of said crank and vinsulated therefrom, a terminal-element mountedin one-of said crank arms and housing and insulated fromthe crank arm, a wire connecting both terminal members, said wire being adapted to pass current from the cells thru one of the terminals of the filament lamp, the opposite terminal of said lamp being in grounded circuit thru said crank arm, and a switch adapted to open and close the circuit thru the filament lamps and dry cells.

i 3. A device of the class described compris'- ing a crank, a bit. head at one end of said crank, a cylinder mounted on the opposite end of said crank, said crank having a pair of off-set arms connected by an intermediate member, a saddle secured to the low? ,er arm, a hemi-sherical housing forming part of said sadd e, said housing having an opening therein, a lens covering said opening, a filament lamp in said housing, arefiector being mounted angular'ly in said housing, a cap minal being mounted angularly and'insulated from the crank arm, and awire connecting the dry cells and terminal.v In testimony whereof I aiiix my signature.
